Question

What happens to glucose once it enters the myocytes? Liver?

a) Glucose is converted into fat in myocytes and broken down in the liver
b) Glucose is stored as glycogen in myocytes and liver
c) Glucose is excreted by myocytes and metabolized in the liver
d) Glucose is converted to lactate in myocytes and stored as glucose in the liver

Answer 1

Glucose is stored as glycogen in both myocytes and the liver, serving as an energy storage molecule. Glycogen can be broken down to release glucose when needed or converted into glucose-6-phosphate for energy production.

Step-by-step explanation:

Once glucose enters the myocytes (muscle cells) and liver, it is stored as glycogen. Glycogen is a polymer of glucose and serves as an energy storage molecule in animals. In the liver, glycogen can be hydrolyzed into glucose 1-phosphate to maintain normal blood glucose levels. In both muscle and liver cells, glycogen is broken down into glucose-6-phosphate, which enters the glycolytic pathway for energy production.
